Take a 92D mainspring and remove 2 turns. Don't believe the hype about light strikes; it doesn't happen with even the hardest primers.
/Been runnin' my 96FS that way for years.
*Edit* Some hard numbers from previous experimentation:
Stock FS spring
Preload: 8.7 lbs
Compression to fire: 11.7 lbs
Stock D spring
Preload: 5.8 lbs
To fire: 9.1 lbs
Modified FS spring (3 turns removed)
Preload: 5.4 lbs
To fire: 8.8 lbs
Modified D spring (2 turns removed)
Preload: 3.0 lbs
To fire: 6.5 lbs

What is the reasoning or logic for switching to such a spring?

The idea is that a DA trigger pull must cock the hammer and a lighter mainspring is easier to compress, hence lightening the pull. Which this mod does beautifully.
I believe (and will go verify one way or the other) that the Wolf #16 is usually
referred to as a replacement for the 92D, but really is not.
If going with Wolf, disregard my advice to take 2 turns off. Do that only with a genuine Beretta 92FS spring.
Yep. #16 Wolf runs about like a factory 92D.
